The Design of Chicken House Electronic Intelligent Lighting Apparatus

摘要

This page proposed an automatic henhouse light filling system which used microcomputer as main control unit. It can be achieved light up in the daytime through the photoconductive resistance induction light intensity is insufficient; illuminated lighting at night in a fixed time. The System to sense and measure the light intensity by using photosensitive resistance and LM358, then compares and output the measured value, and then SCM can control the LED light according to the variation of the output measured value. The System to achieved electricity saving and control the lighting time by using the clock chip DS1302 and batteries, to measure the indoor temperature and humidity by using DHT11 temperature and humidity chip, and to showed the current environment of temperature and humidity values and real time by using the 1602 chip. With the advantages of simple design, easy maintenance, cheap cost, the system can be widely used in the field of poultry breeding industry.
